Just wondering how long it should be before I see this option in update manager. I've made sure I have the latest sources by doing an update, but the Edit tab doesn't show any update. Oh, and I have changed the repositories as well, but that hasn't made a difference (just tried some US and Canadian ones).

Please, check whether your software package mint-upgrade-info is version 1.1.0, because the information on the upgrade path from Mint 18.x to 18.3 has been added in mint-upgrade-info 1.1.0.
There are several was of verifying the installed package version. Here is one of them: Inside a terminal window execute

The screen output of this commandline will reveal which version is present on your system.
Please, post the screen output of apt-cache policy mint-upgrade-info

Uhm. Hardly dare ask so, but ...
You are aware that the option to upgrade your system to Linux Mint 18.3 will be displayed in the Edit menu of Update Manager as a dedicated action item?!
You have to select the item in the Edit menu, in case you wish to upgrade.
Update Manager is not going to display the upgrade option inside the list of updatable software packages.

Old bugs good, new bugs bad! Updates are evil: might fix old bugs and introduce no new ones.

And, yes, I'm aware of the process with update manager. I start update manager from the menu. Just to confirm that this is the right program it is MintUpdate version 5.2.9 (from help->about). Next, just to be sure I select <refresh>. Then I open the <edit> menu and it gives me a bunch of options, mostly grayed out. I'd attach a screenshot but it doesn't appear to be possible to take a shot of a menu since when you open the screenshot program the menu goes away But, that edit menu does NOT have a upgrade version option.

I have a second computer running with the same software for my wife and it shows the same issues.

I'm wondering if this is part of the reason. Nothing in my edit menu is greyed out.
